在CSS中,颜色的用法是有几种的方式来处理,比如像我经常比较喜欢用的红色,就有以下的几种表达方式:
-
#ff0000
-
#f00
-
rgb(255,0,0)
-
rgb(100%,0%,0%)
-
red
-
regba(255,0,0,1)
第一种是16进制的写法,
第二种是16进制的缩写法,
第三种是RGB的0~255的颜色值设置,
第四种也是RGB的方式,只是值使用的是百分比,
第五种使用的是颜色名称,当然这里只能是部分的颜色名称(这里只是一种规定,不可能规定所有的颜色值的名称).常用的: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red,silver, teal, white, yellow.
transparent是透明颜色.
第六种是带了透明度的做法,最后一个参数是设置透明的程度,范围是0~1,数值为浮点数.
而颜色在我们常用的属性里面,主要有字体颜色,背景颜色,边框颜色,颜色渐变方面等.比如下面的CSS:
h1{
font-size: 16px;
color: #ff0000;
}
.bg{
backgroud-color: rgb(255,0,0);
}
.txt {
color: red;
}
等等相关的属性使用.把这些CSS放入到你的CSS所在的位置,刷新页面就会看到设置后的效果.
颜色值的使用,当然需要靠设计师的搭配,程序员才能使用这些特点,更好的使你的应用程序发挥得出色. 就行人还得靠靓装,才能更突出的展现.
